Title: Device for testing toothed gears intended for co-operation, by means of which angular velocity faults occurring during co-running are ascertained
IPC: G01M13/02
Filed: 1934-10-15
Abstract: 444,209. Gauging toothed gears. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES., Friedrichshafen, Germany. Oct. 15, 1934, No. 29503. Convention date, Oct. 13, 1933. [Class 106 (ii)] A device for ascertaining angular velocity faults of co-operating toothed gears by means of a transmission gear connecting them is provided in the transmission with a friction roller interposed between two oppositely inclined cones, the shaft of the roller, upon faulty co-operation of the gears under test changing its position and operating an indicating device. The gear R1 is mounted on a shaft 1 whose axis is stationary while the gear R2 is mounted on a shaft 2 in a part 4 that can be swung about a shaft 3 and clamped by bolts 5 engaging a circular groove 6. The part 4 carries a motor 8 which drives by means of a friction roller 9 a wheel 10 of a friction transmission gear 10, 11, 12, 13, 14. When the wheels 12, 14 are in contact, a small clearance exists between the wheels 11, 13. On moving the wheel 12 out of gear, as shown in dotted lines, by unscrewing the nut 23, the wheels 11, 13 engage, the shaft 3 being mounted on a ball 19 and a spring 22 provided to allow this. Upon the shafts 1, 3 are cones 17 18 of small angle, the cone 17 rotating with the wheel R1 which is driven by the wheel R2 while the cone 18 is driven by the friction gear. Between the cones is mounted a roller 20 engaging both. The roller 20 is carried in a part of the elbow lever 25 pivotally mounted on an arm 27 carried on centres 28 on a slide 29 horizontally displaceable in guides 30 of a vertically movable slide 32 moving in guides 31. Inclined guides 33 serve to guide the slide 29 for adjustment of the arm 27 and roller 20 along the oblique line of the cones. To adjust the slide 32 vertically a screw 35 is turned. The elbow lever 25 engages the short arm of an elbow lever 40 also mounted on the arm 27 a pin 41 engaging the short arm 42 of an elbow lever mounted on the pivot 43, the long arm 44 forming a pen moving over a secondary drum 45. A pointer moving with the slide 32 and indicating over a scale is used in positioning the measuring roller 20 for correct gear ratios. In an alternative construction a mirror 53 carried on the pivot of the lever 40 reflects a beam of light on to an arcuate surface 54.

Title: Improvements in or relating to electric discharge devices
IPC: H01J43/20
Filed: 1936-10-30
Abstract: 484,099. Electron multipliers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 30, 1936, No. 29527. Convention date, Oct. 30, 1935. [Class 39 (i)] An electron muliplier has separate resistances contained in the envelope and connected between certain electrodes for the purpose of establishing a potential between them. As shown in Fig. 5, the upper or accelerating electrodes 21 are parallel with the lower or secondary-emitting electrodes 23, and the resistances 41 are connected between some of the electrodes 23. The upper and lower electrodes are connected together in alternate pairs, and the last acelerating electrode has an extension 27 of wire cloth mounted in front of the output electrode 25. The electrodes are supported by parallel mica strips 29, 31, Figs. 2 and 3, and have lugs 33 bent over the edges of the mica strips and holding the resistances 41.. The strips and electrodes form a conduit, and the strips serve to focus the discharge by reason of the negative charge on them. The discharge may be controlled by a permanent or electromagnet. The upper electrodes are formed with openings 35 to permit caesium vapour to reach the lower electrodes freely during activation. The lower electrodes are of nickel coated with copper by plating in a cyanide bath for five minutes and then with silver by plating in a cyanide bath for one hour. Spacing of the electrodes during the fitting of the mica strips is effected by means of a mandrel. After the electrode assembly has been mounted, the envelope is sealed to a pump and baked at 475 C. for 2 to 3 hours. The electrodes are heated by high frequency current to remove occluded gas and oxygen is admitted by heating a side tube containing mercuric oxide. The first five or six lower electrodes are oxidized with a H.F. oscillator, and the others may be heated separately by condenser discharge. Oxygen is removed and caesium admitted from both ends of the envelope. Lead oxide may be used to prevent over-caesiation.. Specification 477,347 is referred to.

The salts may be sodium salts and are acidified by strong mineral acid, e.g. sulphuric acid. The final refining of the esterification mixture may be by neutralization, e.g. with methanolic caustic potash followed by distillation under vacuum, and fractionation of the distillate, or by extraction with water followed by neutralization with aqueous caustic soda, followed by distillation and extraction of the aqueous zone.

[Also in Group XXVIII] In apparatus for raising liquids carrying solids in suspension, the solids are introduced at 12 into a hopper 8 supplied with liquid through pipe 3 that depends into a coiitainei- 4 connected by pipe 6 to a container 5 connected by pipe 7 to the hopper. Air is supplied through pipe 13, that passes through the container 5 and has a branch 15 therein, and is connected to the annular space 17 from which it passes through holes 19 to the mixing chamber 18 where it aerates and raises the liquid in pipe 9 from the hopper 8 to the separating chamber 10. The apparatus can be used within the pressure spaces of caissons for excavating foundations and the containers 4 and 5 or hydraulic seals for the water supply pipe 3' and the air supply pipe 13, through the branch 15, so that should either of these services fail, the pressure in the caisson will be maintained. Fig. 3 shows an application for use in a caisson in which the water pipe 3 and air pipe 13 depend into a container 25 from which the hopper 23 is suspended on a bearing 34. The hopper 23 has radial channels 24 that have inclined bottoms. Hoses 26 connected to the container 25 are also connected to the arms 24 so that the material is washed into the centre of the hopper 23 past guide surfaces 30 that impart a swirling movement, members 37, 38 being provided to agitate the liquid.

Abstract: 783,177. Heat exchangers. ANDRADE, E. N. DA. C. Oct. 29, 1954 [Oct. 29, 1953], No. 29950/53. Class 64(3) [Also in Group XXVI, XXVII, and XL(a)] Heat is extracted from a hot surface by projecting from an orifice or orifices into a mass of cooling fluid already adjacent the surface, a jet or jets of cool fluid at such velocity as to effect complete turbulence of that mass of fluid. Water, air, or a mixture of gas and liquid may be employed as coolant. For example, if the cooling fluid is water and u is its velocity when leaving the orifice, a is the radius of the orifice, and gamma the kinematic viscosity of the water, the Reynolds number R = u a/gamma must exceed 370, preferably by many times, to produce complete turbulence. The fluid may be introduced through a tube which tapers to a cylindrical orifice, or through a passage which is rectangular or elliptical in cross-section and tapers to a cross-section of similar or different form. In one application Fig. 2, the wall 6 of a tube is cooled by liquid kept in a turbulent state by opposed jets of liquid from orifices 7, 7<1>, which may be slightly out of alignment. Drainage ports 8, 8<1> are provided. The invention may be applied to condensers and heat exchangers in thermal power plant.

Abstract: Succinic acid, or its alkali metal salt, is prepared by the oxidation of an alkali metal salt of a -hydroxy-glutonic acid or of 2:21-dihydroxy-adipic acid, or a mixture of alkali metal salts of these acids, by alkali metal hypochlorite in a alkaline or neutral aqueous solution in the presence of a catalyst, known to be capable of promoting the decomposition of hypochlorites accompanied by the evaluation of oxygen, and the salt of succinic acid obtained converted, if desired, into the free acid.  Specific catalysts are cobaltous nitrate, nickelous sulphate or a mixture of nickelous sulphate and cupric sulphate.  Excess of hypochlorite is advantageous.  On completion of the reaction and removal of the catalyst the solution may be acidified with hydrochloric acid, evaporated to dryness and the succinic acid extracted with acetone. Examples are given.
